Hi Hector,

while these should not be there, they are warnings not errors. Usually they have no negative effect on your Koha installation. If you compare to older versions, you probably see that there are similar warnings in the logs there as well.

Please feel free to make a bug report for these (best one per .pl file) you see those warnings for, so they can be fixed.

Hi, we recently updated to 19.05 and now see a very big number of these errors in plack-error.log, it happens with two very different systems at different libraries.

Is this a known problem for 19.05?

Use of uninitialized value in concatenation (.) or string at /usr/share/koha/lib/Koha/Biblio.pm line 578. Use of uninitialized value in concatenation (.) or string at /usr/share/koha/lib/C4/Auth.pm line 584.

This is a count of the most relevant in the last couple days:
